LEVER MECHANISM.

I To all whomit may concem:

Beiit known that I, NORMAN Areas, a citizen of the United States, residing at New- Straitsville, in'the county of Perry and State of Ohio, have invented certain new wells, for placing a friction driven wheel into and out of engagement with a friction driving wheel; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front View of a mechanism constructed according to this invention. Fig, 2 is an end view of one end of the mechanism; and Fig. 3 is an end view of its other end. Fig. 4k is a detail sectional view of the pin connection of the shaft bearin s which prevents them from revolving. Big. 5 is a detail view showing the slot 42. j

A friction driven wheel 6 is secured on a shaft 7 together with a spool or winding barrel 8 which is used in connection with Y the drilling mechanism provided for drilling wells. The end portions of the shaft 7 are journaled in bearings 9 which are formed of upper and lower halves secured together by bolts 10. Themiddle portion 12 of each bearing is a portion of a ball or sphere. Each bearing has a plate 14: across the lower portion of its end which limits the endwise sliding movements of'the shaft 7.

One of the bearings 9 is mounted in a bearing block 15 having a spherical socket 16 for the spherical portion 12 of the bearing to engage with, so that the bearing may move pivotally to a limited extent in all directions. The bearing block 15 is adjustable vertically in vertical guides 18 formed on a standard 19 having a lower crossbar 20. A removable upper crossbar 21 is secured to the standard 19 so that the bearing block can be placed in the guides.

The bearing block 15 is formed of upper and lower halves, which are secured together by bolts 17.

Adjusting screws 22 engage with screwthreaded holes in the upper and lower crossbars, and their ends hold the bearing block and afford a means for adjusting and sup-.

the lower, half of the bearing block 15,.and'

.lock in positionafter it hasbeen adjusted. f The standard 19'lias feet 25 provided with elongated holes or slots "26, and .27 are bolts which engage with the slots 26", and secure" the standard to a base plate 28. The slots 26 permit the position of the standard to be adjusted horizontally and crosswise of the shaft 7. Inclined stay rods 29 are secured to the upper crossbar 21 and to the base plate 28, and have turnbuckles 30 so, that they may be tightened and placed under tension. These stay rods are arranged at the front and back of the stand ard 19, and they prevent it fromvibrating.

The other shaft bearing 9 is mounted in the upper end portion of a lever 82, which has a spherical socket 33 for the spherical portion 12 of the bearing 12'to engage with.

The upper part 34: oft-the socket is secured to the lower partby bolts 35. The lower end portionof the lever 32 is pivoted by a pin 36 to a forked standard 37 which has guides f 38 at its upper part betweenwhich the lever is slidable. The socket 33 and the shaft bearing 12 are normally arranged on a' can be slid to a limited extent in each direction between the two parallel guides 38' with great facility.

The lever 32 has pro ecting lugs 40 on one side, and 41 is [a cap secured over thesaid lugs by means of a bolt 40, and forming with the lever a vertical slot 42. The

so. I

standard 37 has bearings 43 at its upper part, and 4 1 isa crankshaft pivoted in the I 7 bearings 13, and having a crankpin 45 which engages vwlth the slot.

An operating lever 46 1s secured'to one end of the crankshaft and projects upwardly.- Thestandard 37 has feet &7 provided with elongated holes or slots 18, and 49 are bolts 28 and crdsswise of the shaft 7.

The lever 32 is oscillated by means of the gagement with a friction driving wheel 50, a

portion only of which is shown. Each bearwhich secure the feet l7-t0 the base plate permit the standard 37 to be adjusted ingf9 has a pin 51 on its nnderside which engages with a cross-slot 52 in the socket which supports-it, as shown in Fig. 4.,- and this pin conne'etion'prevents the-bearing frembe ing'reiiolved by the shaft 7.
